METHOD FOR CONTINUOUS WEIGHING OF A CONTINUOUS BRANDFORMED OR MATFORMED MATERIAL, AND AN ARRANGEMENT FOR THE EXECUTION OF THE METHOD

摘要

Abstract of the DisclosureIn a process for the production of mat-formed material it is knownto weight the mat as it moves in a horizontal path on a transport means.According to the present invention a continuously running, band-formed ormat-formed material, such as mineral wool is weighed continuously at a givenpoint, and the sensed weight is used to control the speed of a conveyorarrangement along which the band of material is running. The material issupported and transported along a first driven conveyor and onto a seconddriven conveyor spaced a short distance from the discharge end of the firstconveyor. The first and second conveyors are oriented to form an upwardlyconcave obtuse angle such that the band of material deforms and bends throughan upwardly concave obtuse angle as it passes from the first conveyor to thesecond conveyor. The band of material is continuously weighed as it passesbetween the first and second conveyors by passing the deformed and bentband onto and along a third non-driven idler conveyor located between thefirst and second conveyors and arranged to continuously sense the weight ofthe band passing therealong. The first and second conveyors are driven atequal speeds, but the speeds are varied in response to weight changes sensedby the third conveyor means. The third conveyor means may be in the formof a roller mounted in the space between the first and second conveyors.The method and apparatus of the present invention provide for accurate andcontinuous weighing of the mat material.
